Appearance: The Grimm-Human Synthesis

His body is the result of forbidden surgery and the Dark Brother's magic, creating an aesthetic that blends rogue Atlesian technology with organic Grimm matter.

• The Symbiotic Armor: What appears to be a carbon fiber suit is actually a hardened Grimm biomass that has replaced his skin and muscles. The glowing red lines are not just energy; they are Grimm blood (the dark pool substance) charged with Fire Dust flowing through synthetic conduits.
• The Faceless Mask: His helmet is not a piece of equipment, but a reinforced bone plate fused directly to his skull. The red optics detect not only light, but also the fear and Aura of his enemies, allowing him to see through solid walls.
• Physicality: He moves with supernatural grace. He has no pulse, does not breathe, and feels no pain. He is a biological killing machine that only responds to Salem’s will, though his mind retains the combat instincts of the veteran he once was.

Weapon: "Acheron’s Spine"

His sword has been redesigned to function as an extension of his own nervous system.

• The Living Blade: The sword is forged from Alpha Grimm bone and reinforced with a dark metal alloy.
• Energy Discharge: As seen in his silhouette, the blade emits constant discharges of red electricity. This is not just for damage; every strike drains a portion of the enemy's Aura and transfers it to Project Null to repair any damage to his biomass.

Semblance: "Void Instability"

Due to his hybrid nature, his original Semblance has mutated into something terrifying.

• Ability: He can decompose his physical form into a cloud of Grimm particles and instantly reappear a few meters away. Unlike a technological "glitch," this movement leaves a trail of black smoke and ash that suffocates those nearby.
• The "Perfect" Factor: Lacking a standard human body, he can perform maneuvers that would shatter a Hunter's bones, twisting his limbs 360 degrees or extending his claws in unnatural ways.

Behavior: The Silent Anomaly

Project Null does not speak. He does not mock his enemies or follow complex schemes. He is a force of nature sent by Salem for missions that require total annihilation.

• Isolation: He does not interact with the Dark Triad or other subordinates. Salem keeps him in a stasis chamber within the Grimm Lands, releasing him only when others have failed.
• The Veteran's Ghost: Occasionally, in the heat of combat, he performs a gesture of military respect or an elegant, ancient sword technique—a tragic echo of the life he lost to become this monster.
